Hi, Last year I had similar issue when trying to purchase the licence for the iPad to use as walkabout, no matter how much help was suggested, it would not work on my vista laptop, even adding Mcafee virus checker to the exceptions or disabling it did not help. Finally I tried uninstalling Mcafee completely & tried again following a reboot & this time was successfull with the purchase so I now use Avast virus checker with Spybot & Malware free software as suggested on this forum & all works well. it's worth considering it to see if it sorts the issue out regards Tee
